Despite the fact that sunscreen is a necessity, many myths persist about how and if the product works.

Studies show that wearing SPF 15 or higher daily reduces the risk of developing squamous cell carcinoma. Second most common cause of skin cancer) by approximately 40% and reduces the risk of melanoma by 50%. However, the American Academy of Dermatology recommends using a sunscreen with SPF 30 or higher daily.
Proper application and reapplication of sunscreen is critical to reaping all of these SPF benefits. Below, a dermatologist debunks common myths and misconceptions about this must-have skin care product, and explains exactly how to do it.
Myth 1: You only need sunscreen on sunny days
If you look outside on a cloudy day and think, “I don’t think I’m wearing enough sunscreen today,” think again. “UV rays can be harmful even on cloudy days. Up to 80% of UV rays pass through clouds.So it’s important to apply sunscreen every day, regardless of the weather,” says Shokeen.
Dermatologist Dr. Brendan Camp says it’s a mistake to say you don’t need to wear sunscreen indoors. “Windows allow UVA rays to pass through, which can damage dermal structural proteins such as collagen and elastin, causing sunburn,” he explains.Rain or shine, indoors or out, you need Apply (and reapply) that SPF.
Myth 2: All sunscreens are ‘toxic’
“Sunscreens undergo rigorous safety testing and must meet regulations before they are approved for use,” says Shokeen. “The ingredients used in sunscreens have been evaluated by regulatory agencies and deemed safe.” If you prefer a more “natural” product, look for sunscreens that contain zinc oxide or titanium dioxide. she recommends.
Myth 3: One application of sunscreen is enough for the day
Many people apply sunscreen in the morning and that’s the end of the day, but Shokeen says we need to reapply more often. “Sunscreen should be applied liberally and evenly at least 15 to 30 minutes before sun exposure. Or reapply after sweating or right after swimming,” she says.
Myth 4: Higher SPF Provides Longer Protection
The term “SPF” stands for Sun Protection Factor and indicates how well it protects against UVB rays. Types of rays that cause sunburn. “SPF 30 provides plenty of protection, blocking about 97% of UVB rays, but a higher SPF only slightly increases protection,” he says. “Frequent reapplication of sunscreen is still necessary regardless of SPF level.”
Myth 5: Sunscreen never expires
Sunscreen has the same expiry date as food and cosmetics. “Check the expiration date on your sunscreen. An expired sunscreen can change its consistency and degrade its active ingredients over time, which can affect the effectiveness of your product.” says Camp.
Sunscreens generally last for about 3 years. Many bottles have a designation such as “12M” or “18M” to indicate how long the product will last after opening. Some have a small barcode or icon that indicates the expiration date.
Myth 6: Some sunscreens are waterproof
“There is no water-resistant sunscreen,” says Camp. “American Academy of Dermatology” We recommend using a water-resistant sunscreen. Water resistance means how long the sunscreen lasts on wet skin. ” Sunscreen should be reapplied after sweating or swimming, whether it is “water resistant” or not.
Myth 7: Sunscreen is all you need to protect yourself from the sun
Sunscreen is certainly essential, but it’s not the only way to protect yourself from the sun’s rays. “There is no sunscreen that protects him 100 percent from UV rays,” Dr. Camp says. “Compliment his use of sunscreen with sunglasses, a wide-brimmed hat, UPF clothing, and he avoids the sun during peak hours of the day (10am to 4pm).”
An annual skin check is also an important part of your sunscreen routine. “Regular skin checks and visits to a dermatologist are also important for early detection of skin changes and abnormalities. Taking these proactive steps will help maintain healthy skin and prevent sun damage. It helps reduce the risk of skin cancer and skin cancer,” says Shokeen.
